This invention relates to lint vHues for cotton gins and more particularly to a controlling` means thcref r, and has for its primary V factured and "readily installed in theflues of cotton gins now in common use, and known as brush gins. l

Other obj ects and advantages of the inven-k tion will be apparent during the course of the kfollowing description. Y

In the accompanying drawings, in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a top plan view of a Hue leading to a condenser shown at one end thereof, and

showing a battery of gin stands, each vhavingr i a Hue emptying into thecondenser Hue,

Figure 2 is an enlarged sectionof the con-'- denser Hue and one of the gin stand Hue's con! ,ne'cted thereto, taken on the line 2 2 of Figure'l, looking in the direction of thek arrow,

' Figure 3. is an enlarged, fragmentary, longitudinal section of a condenser Hue showing the mouth of a gin stand Hue in dotted lines and my valve therefor in elevation, and,

Figure 4 is an enlarged detail, perspective view of the valve and fasteners.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates, as a whole, a condenser and press showing the relative position thereof, to a condenser Hue 6, which feeds the same, the end 7 of the Hue 6, opposite to the condenser 5, being closed.

Connected to thecondenser Hue 6, in spaced apart relation, is a plurality of gin stand Hues 8, each leading from a gin stand, indicated as a whole at 9, and each of the gin stand Hues having an open end 10, emptying into the condenser Hue 6, all of the foregoing description being of usual and well known l construction. l

1n the present operation of gms as above described, it often happens thatone of the'v gin' stands becomes temporarily disabled, by

reason of abroken or slippedbelt, or" the like, and during such term of disability,'tlie Hue from that particular gin stand no longer functions as a means for conveying cotton to thecondenser flue, which is common to all the gin stands. At such times, 'the cotton from the remaining gin stand Hues enters' the mouth 1G of the inactive Hue,and lbacks into the brush and saws,l causing ja great dealV of damage to the stand and resultingin a-great loss of time. i Y Y To eliminate this loss of time and damage the disabled gin'stand, whereit winds around to machinery, Iprovi'de the openen'd 10of l. each gin stand Hue 8, with afvalve 1 1,`Wliich may be made of metal, Vwood .orA other/suitable material and may be installed inthe flues of any gin ofthe well known brush gin type'.

he valve l1 may be liinged'or pivo'ted to A the interior surface of the flue`6 by any suitf able means, suoli as strap fasteners 12, which may be' secured to the wall of the Hue 6 byf pivots 13, or thelike, and which may have l rolled edges 14, fitting into recesses .15, formed'in the rolled edge 16 of the valve 11, the rollededges 14 and 16, being in longitudinal alineinent and receiving loosely there-k through a pivot pin l?, the details of the above described assembly being clearly shown in Figure 4.

The valve 11 is arcuate in shape,to conform incontourto the interior of the Hue 6, and

is longer and `wider than the opening 10, be-

ing so disposed within' the flue 6, relative to the opening 10, thatthe opening is completely covered with the valve in closed position. Inoperation', a current of air which is set up in eachI gin stand 9 forces'open thervalve 11 for the corresponding gin stand Hue 8 and` gin stands, from entering the opening 10 and f backing up to the gin stand.

It is to be understoodl that'the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that 4various changes in the shape,

size, and arrangement of parts may be rej sortedrto Without departing froml the spirit of the invention or the scope of the appended claims. v s Y What I claim is':- 1 l. In combination with a condenser flue and a gin standflue openingthereinto, a

`valve for controlling the opening and adapted to be forced open by airto'perinit the pas-V sage'of the contents of the gin stand flue into the condenser flue, said valve being normally closed 'by gravity to prevent the passagel of the contents ofthe condenser iue backing into the gin stand flue.

2. In VCombination With a Condenser flue havinO` anV opening inthe Wall thereof, and a'gin stand flue'emptying through said openvingin'to said condenser iue, a valve of greatthe 'gin' stand flue into the condenser flue.

3. In combination With a gin stand flue and a condenser flue having an opening in the Wall thereof connecting the interiors of said flues, a valve-conforming in contour to the interior Wall in which the opening is formed, and mounted relative to the opening to normally operate bygravity to close the passage from the condenser iiue to the ginstand Hue, and to open into the condenser flue when air is directed through the gin Y stand flue against the valve to permit the Contents of the gin stand iiue to Y'enter the condenser flue.

Il. In coinbinationvwith a plurality of gin stand tlues and a common Condenser' flue hav-V ing an opening in the Wall thereof for Vcommunication With each gin stand flue, a gravity operated valve for each Communicating opening to normally close the latter, each of said valves being hinged Within the condenser `flue longitudinally'thereof to permit the valve to swing in an are transversely of the condenser iue. l

Y In testimony .whereof I aliiX my signature hereto.
